Rebecca's ideal clients are those struggling with eating disorders—Anorexia, Bulimia, Binge Eating, Orthorexia, or ARFID—as well as dancers or athletes navigating performance pressure. They come seeking relief from food rules, guilt, and body image struggles, or needing support fueling demanding training. Rebecca meets each client with a compassionate, weight-inclusive, all-foods-fit approach—creating a safe space to heal their relationship with food, rebuild body trust, and develop sustainable nourishment habits. For performers, she integrates performance nutrition to support energy and recovery without compromising well-being.

Rebecca is a Certified Eating Disorder Specialist (CEDS) supporting eating disorder recovery and performance nutrition for dancers and athletes. With a weight-inclusive, all-foods-fit approach, she helps clients break free from food rules, heal body image, and find lasting peace with food, all through individual, sustainable, evidence based nutrition.

If you're exhausted from fighting your body or trapped in food rules, you're not alone. Whether you're navigating recovery or fueling a demanding training schedule, Rebecca offers a safe, non-judgmental space where you'll feel truly heard. Healing is possible, and a more peaceful relationship with food is within reach. You deserve support.
